No symptoms/anxiety

6+5 today but have absolutely no symptoms, other than feeling a wee bit more tired than usual and my boobs/nipples being sensitive. had an early scan on Wednesday last week, saw heart beat etc. it eased my anxiety initially but now I am back to square one with all sorts going through my head from MMC to something being wrong! Anyone else in the same boat? Really struggling to be positive - had an early loss 2 years ago and I just feel like I cannot enjoy being pregnant because I am terrified something bad is going to happen! 😔
